Classname variable?

[tnhomestead 0]

New to autoIt, so might as well start with a stupid question.I have searched, but cant find an example of what I am doing wrong.

Using winactivate to open some windows. Trying to code a script to keep a bunch of remote desktop connection windows open. IE Click each window every 10 minutes, but want a way to enter the various vps names so the script can click them.

I couldnt find an example, and when run, there is no error. The variable contains the correct value, but nothing seems to happen.

WinActivate("CLASS:Notepad")   ; This works fine
WinActivate("CLASS:$password")   ; This does not seem to work

WinActivate("[CLASS:" & $password & "]")

Many thanks, worked like a charm.
